Abstract: This article,based on Graphic Processing Unit (GPU) picks up and builds a kind of single instruction multi-threads scheduling model.This model is independent of GPU,but is similar in function,has more simple architecture,is easier to be understood and realized,and is convenient to be transplanted into other processor architectures.This article also analyzes the performance of this scheduling model,which shows the attribute of this model and is an important reference for the use and optimizing of this model and transplanting into other processors.
